SOUTH HADLEY, Mass (WWLP) – A Mount Holyoke College professor is being held without bail after an alleged violent attack on her colleague, and friend that she knew for 14 years, over winter break.

Northwestern District Attorney’s Office spokeswoman Mary Carey told 22News, 48-year-old Rie Hachiyanagi was arraigned in Orange District Court on Friday and is being held in the Franklin County House of correction until her next hearing on February 4.

Rie Hachiyanagi charged with:

Carey said Hachiyanagi is accused of assaulting the victim in the victim’s Leverett home from December 23 to December 24, beating them with a rock, fire poker, and garden shears. The victim is expected to survive but has severe injuries.

“People are capable of lots of scary things so I mean unfortunately, that does happen but it is kind of scary to hear that it can happen so close to home.”

According to the police report filed by State Police, the victim stated, in an audio-recorded interview, that Hachiyanagi showed up to her house wanting to talk about her feelings and attacked her. When the victim opened the door to let Hachiyanagi in, the victim said she turned around and Hachiyanagi hit her over the head with “something hard” and then repeatedly hit her over the head.

The victim stated in the police report that she met Hachiyanagi in August 2005 and they were friends.
